Test principle:

By vacuuming the vacuum chamber, the internal and external pressure difference of the sample immersed in water is generated, and the gas escape in the sample is observed to determine the sealing performance of the sample; By vacuuming the vacuum chamber, the internal and external pressure difference of the sample is generated, and the sample expansion and shape recovery after vacuum release are observed to determine the sealing performance of the sample. Comply with GB/T 15171 Test Methods for Sealing Performance of Flexible Packages, ISO and other standards< br />
